We're dividing 706521 by 42 
We want to divide 706521 by 42.

Advancing to step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 42

Step 2:
70 divided by 42 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
If we take 42 away from 70, we end up with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 42

Advancing to step 3:
If we divide 286 by 42, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 34 after subtracting 252 from 286.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 42

Let's proceed to step 4:
42 can be fit into 345 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we take 336 away from 345, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 42

Advancing to step 5:
The number 42 fits into 92 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1682.0
Subtracting 84 from 92 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 42

On to step 6:
42 goes into 81 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 16821.0
If we take 42 away from 81, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 42 fits into 390 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 16821.9
If we take 378 away from 390, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 16821.92
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 16821.928
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 16821.9285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 16821.92857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 16821.928571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 16821.9285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 16821.92857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 16821.92857142, with a leftover of 3.6e-08.
